Description
M/A-COM‘s AT65-0009 is an integrated voltage
variable attenuator containing two PIN diodes and a
passive glass quadrature hybrid. This device is
packaged in a 5 leaded SOT plastic surface mount
package. Maximum attenuation is typically achieved
at 3.5 V bias using the suggested bias circuit. The
AT65-0009 is ideally suited for GSM communication
applications requiring variable attenuation in the 824
to 960 MHz bandwidth.
Electrical Specifications: TA = 25°C, Z0 = 50 Ohms, F = 824-960 MHz
